I'm interesting only for the full stops. Some headings ends with fullstops some of them not. For example, if Heading 1 and 3 ends with full stop but not the heading 2, the result must be {Heading 1., Heading 2, Heading 3..}. I'm not interesting for other abbreviations or spaces in this part for sure. So what i need is to change this to {Heading 1, Heading 2, Heading 3.}. The perfect approach would be, the macro check if heading has full stop and delete it before put them inside brackets, if not then check for the next heading and so on.
